FM 1092 Access Management
Fort Bend County
SH 6 to US 59
The problems to be addressed are heavy congestion, high crashes, connectivity, and lack of active transportation facilities for walking and biking. This 6 mile section of FM 1092 from US 59 in the City of Houston to SH 6 through the cities of Stafford and Missouri City is heavily utilized, south/north, five to seven lane rural and urban section corridor with a CTWLTL (note, south of Avenue E, a two-way two-travel lane with center left-turn lane; north of Avenue E is a two-way center left-run lane, three northbound and two southbound lanes). It is functionally classified as a principal arterial with posted speed limit that varies from 45-50 mph and traffic counts vary > 37,000 near West Airport Boulevard, > 40,000 south of US 90A, and >35,000 near SH 6. The FM 1092 corridor has limited connections to US 59, US 90A, SH 6, and Beltway 8. The roadway network connectivity in the area is roughly 37 square miles and a major roadway grid of only eight roads is present. The need for and value of alternate traffic routes will increase for the continued development of Fort Bend County. Active transportation facilities for walking and biking are limited or missing but there is significant pedestrian and bicyclist activity observed along the corridor. FM 1092 is flanked by commercial and light industrial development as well as single-family residential development. The current driveway density along the corridor exceeds typical standards, with some segments of the corridor having driveway densities over 70 driveways per mile, which significantly contribute to crashes and decrease mobility. The crash rate along the corridor is more than double the statewide average. All intersections in the corridor operate with acceptable levels of service (LOS A to C) with the exception of FM 1092 at Avenue E, which operates at a LOS E during AM and PM peak hours. Other intersections are nearing capacity with a v/c ratio over 0.90, specifically at the Southbound US 59 Frontage Road and at West Airport Boulevard.
1) Expand FM 1092 south of Avenue E from four to six travel lanes;
2) Add 5' bicycle lanes and 6' sidewalks from Roark Road to Dove Country Drive;
3) Add bicycle facility to continue along Roark Road to the West Bellfort Park & Ride and the future keegans Bayou Trail at the point that Roark Road is improved;
4) Construct 13' raised median along the corridor;
5) Extend Curb Island, signage, and striping of Left Turn Only Lane for southbound approach at intersection FM 1092 @ US 59 Frontage Road (southbound);
6) Install crosswalks on all four approaches as well as wheelchair ramps and pedestrian signals at intersection FM 1092 @ West Airport Boulevard;
7) Restripe Mula Road and Greenbriar Drive as 3-lane roadway with two - 5’ bicycle lanes to allow for dedicated left turns at FM 1092;
8) Revise signal operations and timings to support lane geometry and remove split phase operations and Install crosswalks and pedestrian signals at intersection FM 1092 @ Greenbriar Drive/Mula Road;
9) Install crosswalk, three ADA wheelchair ramps, and pedestrian signals as well as restriping at intersection FM 1092 @ Cash Road;
10) Add appropriate signage to designate Cash Road between FM 1092 and Stafford Road as a bicycle route with sharrows connecting to Houston Community College;
11) Install raised delineators in the gore areas between the FM 1092 frontage roads and the FM 1092 main travels lanes as well as improves signage and striping;
12) Install crosswalks, wheel chair ramps, and pedestrian signals at FM 1092 @ Dove Country Drive; and
13) Improve and optimize signal system and operations at FM 1092 @ Promenade Boulevard to allow northbound left-turns when a train is present along the Union Pacific Railroad and add cross walks and countdown ped signals at Hampton Drive and Dove Country Drive. Optimze the signal system along the entire corridor.
The primary purpose of the project is to identify transportation improvements that reduce crashes, improve traffic flow, reduce motorist delay, and to address multi-model/land use context. The improvements will smooth traffic flow, improve travel times, decrease delays at traffic signals, improve air quality, and provide for a less stressful commute thus improving public health, a key goal of the FHWA. The project is anticipated to reduce the rate and severity of crashes. According to the FM 1092 study from IH 69 to Dove Country, implementation of access management results in 187 hours of VHT savings, $10.9M in crash cost savings, and $2.3M in annual travel time savings. Empirical evidence documents the benefits of Access Management treatments. For instance, FHWA's Benefits of Access Management (FHWA-OP-03-066) reports, "raised medians reduce crashes by 40 percent in urban areas and over 60 percent in rural areas." Medians provide pedestrian refuge and better plan how vehicles move through a corridor. The same document indicates left turn lanes substantially reduce rear-end crashes and substantially increase capacity. H-GAC's Evaluation of Access Management report confirms national documentation. The report indicates, access management reduced travel time and delay and reduced driveway-related crashes by 40 to 70 percent, while maintaining economic competitiveness. Construction of bicycle lanes, sidewalks, and signal timing optimization at intersections can reduce about 35 tons and 7 tons of NOx and VOC emissions yearly, respectively, which are ground-level ozone precursors. Minimizing these ozone precursor emissions is essential to prevent ground-level ozone forming and achieve and maintain attainment of the ozone NAAQS for a region. According to the FM 1092 study from Dove Country to SH 6, the implementation of the access management shows 106 hours of VHT savings, $5.2M in crash cost savings, and $1.3M in annual travel time savings for the entire corridor (FM 1092 from Dove Country drive to US 59). The report indicates that signal timing optimization reduced 86% travel time and delay and reduced number of conflicts by 9%, thereby significantly reducing intersection related crashes in the corridor. Analysis conducted at 95 percent confidence level showed that there is statistically significant decrease in all crashes, including vehicle-pedestrian and vehicle(s) only involved, at the installation of pedestrian countdown signals. Adding crosswalks reduced conflicts by two-thirds and pedestrian crash rates by about half. Besides, signal timing optimization at intersections and adding supplemental signal head and signal ahead sign reduced about 10 tons and 2 tons of NOx and VOC emissions yearly, respectively, which are ground-level ozone precursors.

The improvements in this project will make biking more safe because it will limit conflict points thus creating a higher comfort activity. In some locations, we are proposing improved cross walks and the addition of a raised median will provide much needed pedestrian refuge in a high speed, multi-lane corridor. While the corridor does not have a designated bike facility, because of the observed conditions, accommodations will be implemented as part of the project.
